What's a typical PSU wattage that's suitable for x3 5830? Anyone?
I don't have an exact answer but maybe this info will help.
My 'standard' 1.2+ GH/s rig configuration is:
CPU: AMD Sempron 140
Board: MSI 890FXA-GD70
Memory: 1x2GB DDR3 (whatever speed; doesn't matter)
GPU's: 4x5830's clocked to 960/300
PSU: Corsair 950WStandard draw with Kill-A-Watt per rig is 650W, even with the 5830's OC'ed to 960/300.
There's actually head-room to add one more 5830 for 5x5830's with the Corsair 950 if I used PCIe extenders.
Hope this helps.
I use an 8GB USB flash drive to run Ubuntu 11.04 headless using Catalyst 11.6 and phoenix 1.50.
